The write command works only in audio modes 2 to 6.SyntaxTest CommandAT^SNFI=?Response(s)^SNFI: (list of supported s) , (list of supported s)OKRead CommandAT^SNFI?Response(s)^SNFI: , OKWrite CommandAT^SNFI=, Response(s)OKReference(s) PIN ASC0 MUX1 MUX2 MUX3 Last-- ! % % % % ! !Parameter Description (num)(^SNFW)ADC gain adjustable in eight 6 dB steps from 0 dB to 42 dB (0=0dB, 7=42dB, 8 steps of 6 dB).0...7 (num)(^SNFW) 9/10/08Multiplication factor for input samples. Formula to calculate the negative gain (attenuation) of the input signal:Gain in dB = 20 * log (inCalibrate / 32768)0...32767Notes• The range of is up to 65535 but will be suppressed to 32767. Values above =65535 will cause a failure.• The parameter of AT^SNFI is identical with of AT^SNFA.• For use after restart, changed values can be stored with AT^SNFW.• Attention! When you adjust audio parameters avoid exceeding the maximum allowed level. Bear in mind thatexposure to excessive levels of noise can cause physical damage to users!MC35i_ATC_V02.00nConfidential / ReleasedPage 333 of 390
